Abstract: 821,647. Tool and like turrets. WARNER & SWASEY CO. Aug. 21, 1956 [Sept. 7, 1955], No. 25494/56. Class 83 (3). An indexible tool or work-holder for a lathe or other machine tool comprises a base 134 adapted to be secured to a cross-slide. The base has secured thereto an upstanding neck 141 the internal bore of which supports a slidable but non-rotatable pillar 140 and the external surface rotatably supports the indexible turret 135. The embodiment shows a tool-turret for a lathe having upper and lower members 126, 128, respectively, for clamping tools. The lower end of the pillar 140 is secured to a piston 153, the cylinder 136 of which is fed with fluid-pressure through passages 155, 154, to clamp the turret so that teeth 149, 150 are engaged to prevent rotation of the turret. Rotation is effected by fluid-pressure supplied between vanes 164, 165, secured to the turret and stationary vanes secured to the pillar 140. A piston and cylinder arrangement 158, 157, lifts the turret to free the clamping teeth. Indexing is controlled by a hand-operated valve 175 which is urged to neutral position by a spring 179. When the valve is rotated clockwise the turret is unclamped, moved 90 degrees clockwise and reclamped when the hand lever is released. The turret is moved 90 degrees in the opposite direction by opposite movement of the lever.

Filed: 1923-10-16
Abstract: 227,518. Alexander, H. M. Oet. 16, 1923. Separating by gravity.-In separating liquids of different specific gravity for example, oil and water, the mixture is submitted to a preliminary separation, the heavier liquid containing some lighter liquid being withdrawn and delivered in an upward direction into a body of the heavier liquid above which the lighter liquid collects, while the heavier is withdrawn evenly around the bottom of the body. The mixture is delivered into a separating chamber through a number of inlet pipes arranged to discharge at points spaced apart and so situated that local eddies and swirls are reduced to the minimum. The preliminary separating chamber may comprise a conical shield 6 with upper tubular casing 8, heating pipes 17 and oil receiver 9, all as described in Specification 205,935. The mixture, supplied by a pipe 14 to a feed box 10, is passed into the chamber by a pipe 15 which delivers over a dished deflecting plate 16. The water with some oil passes under the bottom of the shield 6 to an annular chamber 36, and thence up pipes 20, several of which are provided, into the secondary separator 22. The ends of the pipes 20 are turned downwards over deflecting plates 21 and are situated at about the height of the centre of gravity of the radial section of the annular chamber 22 and at a distance from the axis of the chamber equal to the radius of gyration. Oil separates and rises past a heating coil 24 and through pipes 25 to the receiver 9. Water rises from the bottom through an annular passage 26. and passes over a weir 27 and through filtering material placed between a perforated plate 28 and a plate 29. It rises in a passage 30 and then filters downward through a suitable medium in an annular chamber 31. The discharge pipe from the lower end of the latter chamber rises vertically to a discharge weir, the column of liquid in this pipe balancing that at the centre of the apparatus.

Regenerators of the kind in which a rotatable annular heat-interchanging member extends through ducts for the air and smoke-gases, this member being constructed of metal plates disposed in planes substantially perpendicular to the plane of rotation of the annular member to form radial passages, and in which the space within the annulus is divided by a partition into two semi-cylindrical chambers communicating through the radial passages with the respective ducts, the annular member is arranged with its axis at right-angles to the fluid supply ducts 29, 29<1>, whereby the fluids enter the semi-cylindrical chambers 31, 32 through one side of the annulus and leave through the opposite side. The annulus 30 comprises annular discs 40 secured together by arcuate U-shaped members 41, the arms of which are riveted to adjacent discs and provided with lugs 42 having notches 46 at their outer ends. Notched plates 44 alternated with similar corrugated plates 45 are packed radially into the members 41 and the notches 46 rare blocked up. The members 41 with the packing 44, 45 form a continuous annulus which is mounted on rollers and driven slowly by gearing 36, 37 within a casing formed by the two ducts 29, 29<1> separated by a partition 33 which is continued within the annulus to form the two semi-cylindrical chambers 31, 32. Several annular members may be mounted coaxially as shown in Fig. 3, and the rotating parts are sealed at the ends by angle bars 34 and at the upper and lower walls of the casing by I-beams 35. As the annulus rotates the respective gases pass through the radial passages between the plates 44, 45 into a semicylindrical chamber 31 or 32 and out through the opposite set of radial passages to the corresponding duct. The air and smoke gases preferably pass in opposite directions. To ensure radial arrangement of the heat-interchanging plates the corrugated plates 45 are slightly tapered towards the centre of the annular member.

An offshore well is drilled and completed with equipment sufficiently beneath the water surface to avoid damage to the equipment by ships. A borehole 32 is drilled from a vessel 11 using a drill string 34 and bits 33, 35. The drill string is guided by a conductor pipe 31 having a wellhead support structure 23, 24 and casing head 36. When a hole has been drilled which is sufficient to receive the pipe it is lowered over the drill string so that the lower end enters the borehole before the end of the drill string leaves it. Guide cables 25, 26, 29 (Fig. 21) are arranged to extend from the wellhead support structure to the vessel, the pipe and structure are lowered until the structure reaches its final position and the pipe is cemented into the borehold by means of a cementing string. A blow-out preventer 56 (Fig. 12) is releasably connected to the casing head, the lower end of a marine conductor 96 is connected to the top of the preventer and the drill string is run through the marine conductor, preventer, and the conductor pipe cemented in the well so that the drilling of the borehole may be continued. After the hole has been drilled to a length sufficient to receive a casing 104 (Fig. 13), the casing is lowered into the well and suspended from a body 105. The casing is cemented in by cement supplied through a string 108 and wiper plug 112 which is finally moved by dropping a ball (not shown) down the string 108 and applying pressure. After the casing has been cemented the string 108, the marine conductor, blow-out preventer and any connections to the structure are withdrawn to the vessel. Two blow-out preventers and a marine conductor are attached to the casing head, and drilling and cementing proceeds for the installation of further casing. After the casing is perforated a single or multiple tubing string is inserted. In the insertion of a dual string (Figs. 17, 28) a guide 194 carrying a tubing hanger 193 and string 192 is first lowered into the well and the second string 196 is then run through the tubing hanger. The marine conductor and the blow-out preventers are removed to the vessel, the tubing strings are raised by means of the guide, the guide is removed and replaced by a complete tubing hanger and a wellhead assembly 207 (Fig. 18) and the tubing hanger and wellhead assembly are lowered and locked to the body 105. The wellhead assembly is closed by a lubricator 206. Specifications 924,904, 948,321, 948,325, 948,330 and 948,331 are referred to.
